1Before use
1-1 For safe use of the product
This section describes correct use of this instrument to prevent safety hazard to the people and of their
properties.
If the instrument is used in a manner not specified by manufacturer, the protection provided by the
instrument may be impaired.
Please read and understand the contents of this instruction manual and make sure to observe following
warnings and cautions.
1-1-1 Preconditions for use
The instrument is a general product of component type that is to be used by mounting it in a panel for
instrumentation inside a room. Do not use it in any other condition.
When using, design a fail-safe on the final product side and review regularly and use the instrument after
confirming the safety of the system. For the wiring, adjustment and operation of the instrument contact a
professional having knowledge of instrumentation.
It is necessary that the people actually using this instrument read this instruction manual, and have
enough understanding of various precautions and the basic operations of the instrument.
1-1-2 Symbol mark
The following symbol marks are used in the instrument itself and in this instruction manual hence
understand the meaning of these symbol marks properly.
Label
Name
Meaning
Alert symbol mark
Place to refer to the instruction manual to avoid
“electric shock” and “injuries”, etc.
Pay extra attention during wiring, inspection and
maintenance.

1-1-3 Important
Warning
To avoid severe accidents, make sure to read and understand the
followings and use the instrument.
Confirm the power supply voltage and wiring
Before supplying the power to the instrument, check that the wiring is correct and power supply voltage
matches with the rated voltage etc.
Install circuit breaker
The instrument does not have a power supplyswitch. Install a circuit breaker that matches the rating
specifications in the power supply of the instrument.
Protection of terminal
To prevent electric shock, provide the terminal of the instrument with safetymeasures such that the user
will not be able to touch the final product directly.
Installing the safety device
Regarding the use of a device that anticipates a big loss due to failure of the instrument and the peripheral
devices, always install a safety device for preventing these losses and implement fail safe design in the
final product. Do not use it in important facilities in which human life, atomic energy, aviation, space etc.,
are involved.
Do not put your hands inside the instrument
Do not put your hand and tool inside the instrument. You may get an injury or an electric shock.
Power cut off in case of suspicion
If there is an offensive smell, a strange noise or smoke or if the temperature increases abnormally, it is
very risky hence cut off the power supply immediately and contact the dealer or our nearest office.
Prohibiting repairing and remodeling
If repairing or remodeling is necessary, contact the dealer or our nearest office. Only the service engineers
appointed by our company will change the parts, do the repairing and remodeling.
Strictly follow the instruction manual
In order to use the instrument correctly and safely, follow this instruction manual. Please understand
beforehand that our company will not at all be responsible for any claims for injury, damage, and passive
damage due to wrong use of the product.

Where there are no vibrations and shocks.
Away from liquids (water etc.).
Away from condensation.
Industrial environment
(Overvoltage category: II, Transient overvoltage: 2500V, Pollution degree: 2)
1-3-2 Surrounding condition
Away from strong noise, static electricity, and electric field and magnetic field etc.
Surrounding temperature within -10 to 50C (Less than 40C in case of closed instrumentation),
surrounding humidity within 20 to 90% RH.
Variation in temperature is less.
Away from corrosive gas, explosive gas, ignition gas and combustible gas.
Away from salt, iron and conductive material (Carbon, iron etc.).
Away from steam, oil and chemicals etc.
Away from dust etc.
Away from the surroundings where high temperature is generated.
Away from places where temperature remains stored (To avoid increase in internal temperature,
ensure the ventilation space. However, avoid direct wind to the terminals, it may cause unstable
indication.)
Lot of space above the upper part of the instrument.
Place where display screen can be easily seen. (This instrument uses LCD therefore if it is seen
from ‘above’, ‘below’, ‘left’, ‘right’ and ‘at an angle’ it may be difficult to see the display screen).
1-3-3 Mounting conditions
Installation altitude is less than 2,000m above the sea level
Mounting posture longitudinal tilting is less than 10lateral tilting is less than 10.
1-3-4 Others
Do not wipe the instrument with an organic solvent (like alcohol).
To avoid malfunctioning of the instrument, do not use cell phones in its vicinity.

2-2 Mounting
Confirm the mounting slot1.
(1) Mounting slot is located at two locations, the top and the bottom of the instrument.
Assemble into the panel2.
(1) From terminal board side, put the instrument into the panel cutout angular hole.
For the waterproof specifications, put attached water-proof packing first then put it into the
angular hole.
(2) Prepare attached mounting brackets (2 pieces). Insert mounting claw to the mounting slots (2
locations; top and bottom) and push it into the panel.
Fix the instrument
3.
(1) Push the mounting brackets into the panel side and fix them.

2-3 Wiring
2-3-1 Precautions during wiring
Warning
To avoid severe accidents, make sure to read and understand the
followings and use the instrument.
Electric shock may occur, make sure to turn OFF the power and perform
the panel mounting and/or wiring operation.
Wiring operation should be done by professional
Wiring should be done by a person having actual experience and basic knowledge of instrumentation.
Mount the terminal cover
In order to ensure safety, after the wiring is done, take measures so as to prevent direct contact with the
terminal of the product.
Exclusive terminal cover of the instrument is available as accessory(Sold separately).
Keep away from strong power circuit and noise sources
In order to prevent adverse effect due to noise, do not place the instrument near a device from which
noise is generated (magnet relay, motor, thyristor regulator, inverter etc.).Also avoid passing the wiring of
the instrument and that of noise generating devices through the same duct.Always keep the wiring away
from each other. Take the necessary countermeasures against noise.
Keep away from the heat generating sources
In order to prevent adverse effect due to high temperature, do not place the instrument near the heat
generating sources. If the instrument is kept near any heat generating source, measurement goes wrong
and finally the life of the instrument is shortened. Pay attention to the surrounding temperature of the
instrument.
Avoid places where there is wind and sudden temperature change, it also causes an error in
measurement. Take necessary measures to avoid such surrounding environment.
Unused terminals
Do not connect anything to the unused terminal. Instrument may get out of order.
Countermeasures against erroneous output at the power ON
When power is ON, sometimes the output related signal may be momentarily output when the instrument
is starting normally. Take necessarycountermeasures by using an external circuit.
